A fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids. Traditional fire hoses are lined with rubber and wrapped with a braided linen outer surface. Advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or a nozzle to increase the liquid spray pressure.
